Title: OFDMA Communication System
Inventor: AWAD YASSIN ADEN
IPC: H04L27/26
Filed: 2007-03-20
Abstract: An OFDMA communications system is described in which user devices are allocated sub-carriers on which to transmit uplink data to a base station. Control data defining the allocation of sub-carriers is transmitted on a control channel using a first subset of sub-carriers. ACK/NACK messages fro each user device are transmitted over an ACK/NACK channel that is separate from the control channel using a second different subset of sub-carriers. The ACK/NACK messages for the data transmitted on the uplink are transmitted by the base station on sub-carriers that depend on the sub-carriers used to carry the uplink data. A direct mapping function is preferably used to determine the sub-carriers to be used for the ACK/NACK messages from the uplink sub-carriers. In another embodiment, the ACK/NACK messages are transmitted to the user devices on sub-carriers that are previously identified to the user devices, preferably by transmitting one or more index values to the user device in a control channel thereof.

Title: Magnetic memory with intersecting nanowires through which domain walls can be propagated with data stored in the chirality of domain walls
Inventor: COWBURN RUSSELL PAUL
IPC: G11C19/08
Filed: 2007-05-09
Abstract: A serial magnetic mass storage device and associated data storage method is provided based on magnetic nanowires that support single magnetic domains separated by domain walls. Each data-storing nanowire 100 has a plurality of crossing data-clocking nanowires 110 along its length, forming cross junctions 115 that constitute domain wall pinning sites. Data is fed through each data-storing nanowire by moving the magnetic domains under the action of a field applied to the data clocking nanowires that alternates between alignment and anti-alignment. This causes the domain walls to be pinned at successive intersections of the data-storing nanowires with crossing data-clocking nanowires. The data is encoded in the chirality (principle magnetization direction) of the domain walls, with up and down aligned transverse domain walls being used to encode 0's and 1's. Alternatively clockwise and counter-clockwise orientated vortex domain walls may be used. Data is clocked into each nanowire with suitable nucleation generators 126 capable of nucleating domains with domain walls of pre-defined chirality. Data is clocked out of each nanowire with suitable magnetic field sensors 128 that sense the chirality. Three-dimensional arrays can be formed by providing a number of layers of this arrangement (see figures 13 to 16).

Title: Nail varnish applicator
Inventor: MARZUOLI SHARA LOUISE
IPC: A46B11/00
Filed: 2007-11-21
Abstract: An applicator 17 for nail varnish comprises a reservoir 19, a brush made up of a plurality of bristles 2, a passage or opening 20 connected to the reservoir, and a compressible suction bulb 21, which is used to draw liquid nail varnish into the reservoir through the opening 20 and to deliver it back to the brush for subsequent application to a nail. The applicator may incorporate a screw threaded cap 24, such that the combination is adapted to seal a neck of a container 25 for nail varnish. Compressing and releasing the bulb 21, with a substantial part of the brush immersed in the container, draws nail varnish into the reservoir which can then be applied to several nails without refilling. The bristles 2 can be arranged in a curve and the concave portion of the curve faces the opening 20. Optionally the bristles may be arranged such that they define a hollow shape surrounding the passage or opening. The description further discloses a method of forming this bristle arrangement by inserting the bristles into an aluminium tube, crimping the tube flat and then curling the flattened tube to produce a hollow brush element.

Title: Thermoacoustic device
Inventor: WATANABE YOSHIAKI
IPC: F25B9/00
Filed: 2007-02-21

Title: Provision of Cryptographic Services via an API
Inventor: FRENCH GEORGE
IPC: G06F21/60
Filed: 2009-06-22
Abstract: An encryption service system comprises an application programming interface (API) that receives encryption or decryption requests from calling applications "User A", "User B". Each request uses a simple sentence construct to identify the encryption or decryption operations to be performed on specified input data and the origin and target of the data. A cryptographic server CS determines, for each request, an encryption policy to be applied and requests that cryptographic service providers CSPs perform the requested cryptographic services. Policy-based cryptography may be extended to a key server KS which supports the distribution of asymmetric or symmetric key material, defined by a key usage policy. Key server KS may receive a key request from the cryptographic server and reply with an encrypted key. In other embodiments, the cryptographic server may receive a pre-fetch request from a calling application through the API and, in response, load a set of keys from the key server into a local key store. The API separates the calling applications from the encryption mechanism thereby avoiding the need to alter application code or the wholesale migration of encrypted data from one key mechanism or algorithm to another.

Title: Improvements in or relating to winding machines for thread, yarn and the like
IPC: B65H54/38
Filed: 1931-04-02
Abstract: 375,863. Winding yarn &c. on cops &c. UNIVERSAL WINDING CO., 95, South Street, Boston, U.S.A.-(Assignees of Swanson, E. R. ; 62, Waldron Avenue, Cranston, Rhode Island, U.S.A.) April 2, 1931, No. 10008. Convention date, Jan. 27. [Class 120 (ii).] In a winding machine for yarn &c., comprising a driving element, such as a drum for rotating a yarn receiver on which a package is being wound, a traverse mechanism, and an epicyclic differential mechanism for imparting an alternately accelerating and decelerating speed to one of the winding elements to disrupt the synchrony between the motions of the package and the traverse mechanism, the driving shaft imparts to a planet pinion of the differential mechanism a translatory motion between the sun wheel on the driven shaft and a ring gear which receives an oscillatory motion from a reciprocating crank and so alternately accelerates and decelerates the speed of the driven shaft. A machine frame 2 supports, by means of pillars 7, a driven shaft 11 on which are mounted a number of driving drums 10, each in contact with a cop &c. C on a hinged and weighted spindle 15, the drums being formed with helical traverse grooves 8, 9 for the yarn. The shaft 11. is driven by a coaxial shaft 25 mounted in the head 38 of a pillar 39 and rotated, by a motor 5 through gears 21, 22, in a hub portion 35, Fig. 4, of a casing 32 which is itself mounted to rotate in the head 38. Secured to the inner end of the shaft 25 are arms 45 in the ends of which stub shafts 50 are mounted and carry planet pinions 55 meshing with a sun wheel 70 secured to the end of the driven shaft 11 and with a ring gear 60 secured to the inner surface of the casing 32. The casing 32 is in two parts, one, 33, integral with the hub 35 and the other annular part 34, abutting the first part where the ring gear 60 is disposed and making an oiltight joint therewith. The annular part 34 is journalled on the hub portion of the sun wheel 70 and secured by screws 65 to the part 33. Bolted to the annular casing member 34 is a sleeve 91 formed with a projection 94 for the reception of a wrist pin 95 by which a connecting rod 125 is secured to it. The other end of the connecting rod 125 is rotatably mounted on the crank pin 115 of a two-part crank shaft 110 rotated very slowly by a gear 42, on the end of the shaft 25, through a train of gears 130, 138, 140. In operation, the slow oscillation of the casing 33 and ring gear 60 imparts an alternately accelerated and decelerated motion to the drums 10, but the moment of inertia of the cop or yarn package is such that this temporary variation is not imposed upon it as well, and consequently there results a disruption of the harmony between the 'speeds of rotation of the drums and the packages which avoids the formation of " ribbon" winds. The machine may be adapted for use with a reciprocating traverse mechanism or with a drum winder having a separate traversing drum.
